OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 248,055, dated October 11, 10881, Application tiled March 10, 1881. (No model.)

To all whom it may concern Be it known that I, JAMES OLD, of Allegheny, in the countyof Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Oil-Cups; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in oil-cups; and it consists in providing the body of the oil -cup with a screw-cap, which is divided on a plane forming an arc of a circle, with the upper part of said cap held in place by a yoke pivoted to the lower part, .and all so' arranged with relation to the body of the oillcup that by moving the yoke laterally the upper part of said cap will move with it over the lower part on the plane oi' division between vthe two parts, and thereby allow ingress into the body ofthe cup, all ot' which will hereinafter more fully appear.

To enable others skilledin the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part ot' my specification, Figure lis a front elevation of my improvement in oil cups. Fig. 2 is a side elevationof the same. Fig. 3 is a vertical section ofthe same at line y ot' Fig. 2.

In the accompanying drawings, A represents the body ot the oilcup, which may be made in any desired form. The upper part of the body A is furnished with screw threads, as shown at a in Fig. 3. The body A is provided with a cap, B, which is divided into twov parts, b c, on a plane forming thearc of acircle, as shown in Fig. 2 at d, the center or axis of said circle being at e, the point of pivot of the yoke C, which is pivoted to the lower part, o, ot' the cap B, which part is furnished with screw-threadsf, adapted to the screw-threads a on the upper part of the body A. The part b of cap Baisheld in juxtaposition to parto by means'of a screw, g, which passes through the yoke C, as shown in Fig.3. On the upper part ofthe screw g is a wooden-ball handleyD, held to the upper part of the screw g by means of a screw, h. On the lower part of the body .A is a hollow nipple, k, furnished with screwthreads for attaching the oil-cup to the article or mechanism to be lubricated.

In the oilcup hereinbefore described the In operating my invention the ball-handle is slightly turned, which will turn the screw g and relieve the part b from pressure on the part c; then,'by moving the yoke C sidewise, the part b will move with the yoke C, so that ingress maybe had into the body A of the cup for supplying it with oil. The lid is brought back for the Vpurpose ot' closing the cup by moving back the yoke C, and then slightly turning the screw grwhen it is desired to hold the part b rmly to its seat on the part o. Care should be taken to have the joint d between the parts b and c made on the plane of the arc of a true circle, the center or axis of said circlebeing the point of pivot of the yoke, as hereinbefore stated. By placing the journals alittle off the cen ter ofthe circle obviates turning the handle, as it tightens Vin coming to the distant point. f

Having thus described my improvement, what I claim as of my invention, is-

1. In an oilcup, the lid fitted to the body of the cup on a plane which forms the arc of a circle, and held in position and operated through the medium ot' a pivoted yoke, substantially as herein described, and for the purpose set forth.

- 2. In an oil-cup, the lid or cap constructed in twoparts, the line of division between said parts being on a plane which forms the arc of a circle, said parts being held in juxtaposition and manipulated through the medium of a yoke pivoted to lowerone ot' said parts, which is screwed upon the body oi' the cup, substantially as herein described, and for the purpose set forth. I.

3. In an oil-cup,the combination ofthe body A, cap B, yoke C, and screw g, having a handle, D, constructed, arranged, and operating with relation to each other substantially as herein described, and for the purpose setforth.
